Managing the Apache Process
Now that you have your web server up and running, let's go over some basic management commands.
To stop your web server, type:
sudo systemctl stop apache2
To start the web server when it is stopped, type:
sudo systemctl start apache2
To stop and then start the service again, type:
sudo systemctl restart apache2
If you are simply making configuration changes, Apache can often reload without dropping connections. To do this, use this command:
sudo systemctl reload apache2
By default, Apache is configured to start automatically when the server boots. If this is not what you want, disable this behavior by typing:
sudo systemctl disable apache2
To re-enable the service to start up at boot, type:
sudo systemctl enable apache2
Apache should now start automatically when the server boots again.
